Title: Manufacturing method for buried contact in SRAM
Inventor: CHEN MING-I
IPC: H01L21/768
Filed: 1998-09-02
Granted: 1999-10-21
Abstract: A kind of manufacturing method for buried contact in SRAM which is after forming the buried contact, to proceed the oxygen ion implantation on the area need to be formed source/drain at the proximity of buried contact; employ the high temperature on deposition polycrystalline silicon or the laser to process the oxygen ion implantation area for oxidation and form the silicon oxide to protect the substrate.

Title: Sealed type compressor
Inventor: NIIHARA OSAMI
IPC: F04B39/00
Filed: 1998-12-15
Granted: 2002-05-11
Abstract: An attempt has been made to prevent damage of a hermetic terminal and to improve pressure-resistance strength of the welded joint of connecting pipes in order to provide a sealed housing 4 having a pressure-resistance strength high enough to allow use of a high-pressure alternative refrigerant. For this purpose, ring-shaped metal members 15 and 23 are welded to the outer peripheries of the welded joints of a hermetic terminal 8 to be hermetically welded to an upper end plate 1 of a sealed housing 4 and a discharge pipe 10. As a result, in the event the internal pressure of the sealed housing 4 increases and the upper end plate 1 deforms in the shape of a sphere, the ring-shaped metal member 15 on the outer periphery of the welded joint of the hermetic terminal 8 suppresses the deformation of the hermetic terminal 8 thus preventing damage of a glass seal 12 of the hermetic terminal 8, and the ring-shaped metal member 23 on the outer periphery of the welded joint of the discharge pipe 10 decreases the tensile stress produced in the welded joint of the discharge pipe 10 thus improving the pressure-resistance strength of the connecting section of the discharge pipe 10 thereby providing a sealed type compressor having a sealed housing 4 with a sufficiently high pressure-resistance strength.

Title: Method for the integration of fuel cells into electrochemical plants
Inventor: FAITA GIUSEPPE
IPC: H01M8/06
Filed: 1999-03-31
Granted: 2001-04-21
Abstract: The invention describes a method for the direct connection of fuel cells to electrolyzers of electrochemical plants producing hydrogen as a by-product. The by-product hydrogen is fed to the fuel cells and the electric energy thereby produced is transferred to the electrolyzers, with the consequent saving of the overall energy consumption. The direct coupling avoids the need for DC/AC converters or voltage adjusters and may be effected either in series or in parallel. In the latter case the fuel cell are assembled in modules, the number and voltage of which is regulated by means of interrupters activated by computerised control and supervision system. As an alternative, the voltage of the modules may be varied by varying the pressure of the air fed to the fuel cells.

Title: A word line resistance reduction method and design for high density memory with relaxed metal pitch
Inventor: KIRSCH HOWARD CLAYTON
IPC: H01L27/105
Filed: 1999-04-21
Granted: 2001-09-01
Abstract: A method and design for stitching polysilicon wordlines to straps formed of interconnected metal line segments formed in two or more metallization levels. Each strap comprises a continuous conductive metal line passing alternatively from one metal layer to another in a selected sequence. The sequence of segments in each strap alternates in phase with the sequence in next nearest neighbor straps but may be in phase with second nearest neighbor straps. Thereby the pitch of strap segments on each metallization level is at least twice that of the subjacent polysilicon wordlines. The total length of each metal in each strap is the same in all straps. This arrangement allows the use of metals having different resistivities in each strap with all the straps having identical overall resistance. The metals used in the two or more levels may also have different minimum design rules without compromising the identical overall performance of all the straps. In a second embodiment a method and design is described for doubling the length of polysilicon sub-wordlines in a sub-wordline memory array without reducing performance by connecting sub-wordline to sub-wordline decoders by metal straps connected to the sub-wordlines midpoints.

Through plural preserved battery contacts, plural kinds of switch variations are made such that it is capable of directly determining the battery kind parameter value from a small amount of used battery kinds without the need of using memory to store data. In the invented method, the external current source can be used to add a current to the battery set for generating a voltage drop variation of terminal voltage, which is then added to the original voltage for evaluating the equivalent internal resistance of the battery. In addition, the equivalent internal resistance is proportional to the battery fully loaded capacity (FCC). Through the relationship between the horizontal axis (internal resistance) and the vertical axis (FCC), the degradation parameter value of the battery can be directly obtained without the need of using memory. In the invented method, by real time detecting the terminal voltage value of battery and using one-to-one percent relationship between the terminal voltage value and the remaining voltage of battery, the percent parameter value of the battery remaining voltage can be obtained directly without the need of using memory.

Title: Selective gain adjustment to aid carrier acquisition in a high definition television receiver
Inventor: BOUILLET AARON R
IPC: H04N5/44
Filed: 2000-07-14
Granted: 2002-07-21
Abstract: In a receiver for processing a vestigial sideband (VSB) modulated signal containing terrestrial broadcast high definition television information and a pilot component, and for which multipath interference can lead to significant attenuation within narrow bands of the received signal spectrum containing the pilot tone of an advanced television systems committee (ATSC) high definition television (HDTV) broadcast signal, it has been found desirable to amplify the input signal in order to achieve synchronization of the receiver's phase-locked loop to the received pilot tone. Once this initial acquisition has been established, the amplification applied to the received signal can be reduced to a level appropriate for remaining blocks in the demodulation chain without upsetting the pilot tone synchronization. Thus, according to the present invention, the gain applied to the received ATSC VSB signal is set higher during pilot tone acquisition than it is during the remaining stages of demodulation.
